Murphy's parents Sharon Murphy and Angelo Bertolotti have apparently always refused to believe their daughter died from pneumonia. Angelo had a separate lab test blood, hair and tissue samples in 2012.

The lab report suggests that heavy metals found in Murphy's hair could have been caused from ingesting rat poison.

"Ten (10) of the heavy metals evaluated were detected at levels higher that the WHO [The World Health Organization] high levels. Testing the hair strand sample identified as back of the head we have detected ten (10) heavy metals at levels above the WHO high levels recommendation," it says.

The next part of the report implies that Murphy might have been poisoned by someone.

"If we were to eliminate the possibility of a simultaneous accidental heavy metals exposure to the sample donor then the only logical explanation would be an exposure to these metals (toxins) administered by a third party perpetrator with likely criminal intent."
